Abstract: Electric parking brake devices are configured such that a parking lever is driven by an electric actuator. The electric actuator is provided with: an electric motor drivable in a forward/reverse direction and operationally controlled by a motor control unit according to rotational loads; a conversion mechanism capable of converting a rotational motion into a linear motion, moving the parking lever from a return position toward an operating position through forward rotation of the electric motor, and moving the parking lever from the operating position toward the return position through the reverse rotation of the electric motor; and a load applying mechanism (a stopper and a disc spring assembly) for applying a predetermined rotational load to the electric motor by driving a constituent member of the conversion mechanism after the parking lever is moved from the operating position to the return position through the reverse rotation of the electric motor.

Abstract: A brake temperature detection device is configured detect brake temperature more accurately. In a situation in which the temperature in the vicinity of the brake has risen above the atmospheric temperature, indicated by a value read off of the detection signal of the temperature sensor, for example when traveling in congested traffic, a value to correct atmospheric temperature is determined, and atmospheric temperature is corrected on the basis of that atmospheric temperature correction value. Subsequently, brake temperature is calculated on the basis of the corrected air temperature. As a result of this configuration, it is possible to have the calculated brake temperature approach the actual brake temperature. This makes it possible to detect brake temperature more accurately.
